The original data are generally sampled, and the sample will not be very large. The most basic ones are format, duplicate checking, etc. Then, when checking the quality, whether the original data will be run depends on the specific situation at that time; For example, science and engineering or computer design majors may need to run programs or background data during the demonstration; However, only when there is enough time or special inspection, other majors will be required to check these key indicators.
Then, in order to avoid the lack of summary or data loss afterwards, it is safer to prepare an original data, such as basic data such as investigation, finance or operation.
